What is it?

ThunderPack is a compact programmable microcontroller board with an integrated battery, power management system, ARM microcontroller, USB bootloader, 4 high-power PWM outputs, and 12 GPIOs.

Why did I make it?

After years of manually wiring together portable LED controllers that consisted of a lithium battery, charge controller, power switch, and an Arduino nano (or similar), I wanted something better. I always found those early versions to be janky and fragile -- not to mention that damaging the pouch cell battery might make it explode! This board has everything I need with room to expand.

Board Features

• 32-bit microcontroller running up to 100Mhz (STM32F411xx)
• High-capacity 18650 lithium battery with an integrated 800mA charger.
• 4 high-current PWM outputs (2.3A per channel!) with a PCB LED on each.
• Additional 12 GPIOs (USART, I2C, SPI, USB, etc)
• USB bootloader
• Tactile on/off switch (max current 1A/12V)
• Tactile user button with built-in debounce circuit
• Breadboard friendly
• Supports Arduino & CircuitPython.
• Durable AF! (Put a tube of heat shrink around it for a super easy case if you'd like.)

WARNINGS

If you use your own battery it MUST a built-in protection circuit. The ThunderPack board does not have ANY battery protection built-in.

Includes

• 1 ThunderPack board
• (optional) Battery, if selected with the product.

Does NOT include

• A USB cable. Because you probably have too many USB cables from every other electronic purchase you've ever made. You're welcome.
